iMPROVEIViENT lN CARDING'MACHINES.

Specification forming part of Letters Patent No. 21,364, dated August 3l, 1858.

T0 @ZZ whom it may concern:

Be it known that we, CHARLES E. PRICE and JOSEPH HAYTHORN, of Thompsonviile, in the county of Hartford and`State of Connecticut, have invented a new and useful lmprovement in Carding-Wiachines-for Carding Cotton, Wool, or other Fibrous Substances; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in whchf VFigure l is a side view of part of the framing and the dofferof a carding-machine, showing also the application of ourinvention. Fig. 2 is a planotl the same.

Similar letters of reference indicate corresponding parts in bot-h figures.

This invention consists in the employment of a revolving spirally grooved or threaded cylinder applied below the comb, which removes the fleece from the doffer, and near to To `enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.'

A is the framing of the machine. B is the doffer, which is intended to be applied and operated in the usual manner. l

C is the comb, which removes theiieece `fromthe doffer, attached to va rock-shaft D, andhaving the usual vibrating motion.

E is the spirally grooved or threaded cylinder, made of wood or metal, or of wood with the tops of its threads faced with metal, the said cylinder being furnished with journals which are fitted to rot-ate in suitable bearings in the frame A, and being arranged nearly close to and parallel with the dolter i below the comb C.

P is the mbe through which the sirven is conveyed by the spirally grooved or threaded lVitnesses:

cylinder, said tube being Aarranged with its axis parallel to those of the dofter and grooved Or threaded cylinder ll, and having a funnelmouth which occupies a position above and near one end of the cylinder E, the said tube being held in a bearing a on the top of thc frame. y

The cylinder E receives a continuons rotary motion from a band Z9, which runs toa pulley c at one end of it, from another pulley cl on a shaft G, which is arranged parallel with thev doffer in' suitable bearings, and which derives rotary motion from the doier through a band e, running to a pulley g at one end of it, from a pulley fon the doiTer-shaft. The tube F- derives rotary motion from the shaft G through a band 7i, running froma pulley t' on saidshaft to a pulley j on said tube. The

comb rock-shaft D also derives the necessary.

motion through' a rod m, running to a crank Zon one end of it, from an eccentric wristpin 7c on the said shaft.

The fleece as it is struck from the doffer by the comb C is deposited upon the-spirally grooved Or threaded cylinder, through the action of whose spiral groove or thread, produced by its rotary motion, the fleece is conveyed in the form of a sliver tO and through tube F, whence `itpasses to a can or other receptacle, receiving in its passage through said tube a slight twist, which gives it strength and tenacity. l

lVe are aware that an endless apron has been used as a carrier for the purpose of removing the fleece athwart the doffer, and We are also aware that aV spiral conveyer is of familiar application in machinery; therefore we do not claim, broadly, either the endless belt Or spiral conveyer; but

` That we claim as our invention, and desire to secure by Letters Patent, is-

i The spirally grooved or threaded cylinder E, applied in the manner substantially as described, in combination with the doffer and comb and with a tube F, to operate as set forth.
